Motor Deposition TRIZ Cases
- Switchable Wheel Assembly for Multi-Mode ROS Educational Cars
A detachable wheel-type component and steering lock let one ROS car switch wheel forms and driving modes without rewiring or replacing full modules.
- Hollow Shaft Drivetrain Coupling for Compact All-Wheel Drive
Nesting a coupling element through a hollow shaft output element reduces gearbox-to-transfer-case distance while accommodating radial and axial deflections.
- Hydraulic Throttle Device for Hydrostatic Wheel Hub Motor
Fixed throttle gap walls prevent particle ingress into the seal while a rotary seal isolates components to maintain sealing integrity.
- In-wheel Motor Drain Plug Shielding via Lower Arm Mount
Positioning the in-wheel motor drain plug behind the lower arm mounting portion shields it from flying stone damage while maintaining accessibility.
- Chebyshev-Lambda Suspension for Constant Lateral Wheel Distance
A Chebyshev-Lambda mechanism maintains constant lateral wheel distance during vertical suspension travel.
- Adjustable Hub Wheel Mechanism for Active Terrain Adaptation
A wheel with an adjustable hub mechanism generates leverage force by deflecting the hub, enabling active terrain adaptation without additional drive systems.
- In-wheel Motor Assembly with Opposite Torsion Gears
Opposite torsion angles in planetary and counter gears cancel axial loads, reducing gear count and manufacturing cost while maintaining torque.
- Articulation Actuator Torque Control for Convoy Sway Damping
An articulation actuator applies variable torque to damp sway movements in road vehicle convoys without braking the wheels.
- Electric Drive Motor Integrated Link for Wheel Suspension
Integrating the electric drive motor into the suspension link reduces moment of inertia and improves cooling while maintaining driving dynamics.
- In-Wheel Motor Suspension Shock Absorber Inclination
An inclined shock absorber connects via a link member to secure stroke length without elevating the motor case or restricting axle space.
- In-Wheel Motor Suspension Asymmetry Reduces Bending Load
Asymmetric coupling positions in a trailing multi-link suspension minimize moments from in-wheel motor output, decreasing toe change and component loads.
- Heavy Vehicle Driving Assembly with Independent Wheel Hub Motors
Independent electric motors at each wheel hub eliminate the central differential, reducing ground clearance and increasing loading capacity.
- Independent Drive Assembly Vibration Isolation for AGV Motor Lifespan
An independent drive assembly uses an auxiliary arm and vibration absorbing element to isolate motor stress from ground impacts.
- Spherical Assembly Propulsion via Rotating Weights
Rotating weights inside a spherical assembly create gravitational moments that propel the vehicle, eliminating tire slippage on low-friction surfaces.
- Drive Unit Steering via Differential Torque and Passive Chassis
Differential wheel torques steer the chassis passively, eliminating separate motors while maintaining stability on uneven terrain.
- Coincident Axis Suspension for Compact Driven Wheel Packaging
A suspension uses a connecting shaft as both pivot and drive axis to nest gears inside the wheel rim.
